To all whom, it may concern:

Beit known that l, CLARENCE L. Coller, a citizen of the United States,residing in the city of Richmond, in the county of Wayne and State ofIndiana, have invented new and useful Improvements in a Combined Doorand Automatic Closing Means Therefor, of which the following is a comlete and exact exposition, suoli as will enab c others skilled in theart to which the invention relates to make and use the same, when takenin connection with the accompanying drawings.

' My present invention contemplates more particularly the combining of adoorof the character shown with independent and automatic means forclosing the door under ex traordinary conditions, as in the event ofire, at the same time leaving the door free to be o erated at all timeswithout interference of t e parts.

Another object is to provide a fire-door applicable to o enings leadinginto brick or otherI iireproo elevator-shafts and also being applicableas a freight-house or factory doorl Another object is to provide a doorinvolving simplicity of construction, ease of operat on, requiring smallspace for its installation and operation, occupying only,T a space equalto the thickness ofthe door plus the track above the opening, andproviding a doorand automatic operating means therefor which canbe madeat a comparatively low price. 1

One manner of carrying out the objects of my invention is shown in theaccompanying two sheets of drawings, in Which- Figure 1 shows anelevation ofxny invention with thedoor open and the automatic mechanismset ready for operation. Fi 2 is a detail Sectional view taken on theline X X of Fig. 1. l' Fig. 3 shows an elevation of my invention withthe door closed and the automatic mechanism released and in the positionin which it would be after having per formed its work. Fig. i is edetail front view of the releasin device. Fig. 5 is a detail side viewof the re easing device, and Fig. 6 is a detailsectional View taken online Y Y of `vertical side Wall B, the door-opening C, the

Hoor-line, and D the upper oists of the bniidglhe numeral 1 denotes myire-door adapts ed to close the opening B. Extendin up vertically fromthe lloor (I to the top oipand on the right and leithand of the openingB and permanently secured to the face of the wall A are thechannel-tracks 2 and 3, respeetively. Extending out horizontally arallelwith the joist D and extending from t 1e level of the to s oftthechannel-tracks 2 and 3 and of a less istancc apart are the tracks 4 and5, which are substantially of saine length as is the door 1. The innerends of thc tracks 4 and 5 are secured to the wall A, and their outerends are supported by one or more hangers 6 and 7, which are suspendedfrom the joists l). The

-said tracks 4 and 5 are spaced spart and held in proper relationshipwith cach other by the rods 8 and 9.

`Mounted on the respective right and left upper corner portions of thefece of the door A1 are the vertical straps 10 and 11, which extendslightly above the upper edge of the door and are rovided withhorizontal ivot openings in t ieir upper extension, as s iown, toreceive the pivote bolts l2 and 13, respectively.

Monnted on the tracks 4 and 5 ere the rc- `spec-tive pairs of trucks 14and i5, each heving its dependent hanger-bar 16 and .17, respectively,and the lower ends of said bars 16 and 17 are pivoted on the respectivebolts 12 and 13, whereby the door 1 is suspended suhstantially as shown.Secured Khorizon tally to the lower right and left corners of the door 1are the straps 18 and 19, respectively, which straps extend eronnd thedoor'the thickness thereof, which latter portions carry each an axle, onwhich axles are the respective rollers 20 and 21, said rollers beingformed to neatly i'it the respective channel-tracks 2 and 3 in whichthey are adapted to travel, nach roller being rovidcd with a flangeextending out around) from the inner edge of their oriphcries, shownmost clearly in Fig. ti, W ereby the ends of the axles are preventedfrom contacting with their tracks. i

Mounted on the same axles with the rollers 20 and 21 between therollcrand the strap are the respective right and left links 22 and Secured inthe upper ends of the respec Ytive links 22 and 23 are the ends of there* spective cables or the like 24 and Upon the well A are permenentlylocated the sheaves 26 and 27, over which extend the respective cables24 and 25, as shown, and said cables then extend to and ere secured inIIO . door.

their respective counterbalance-weights 28 and 29 for the doors.

It is now apparent that the door being closed, as in Fig. 3, by ullingforward `onthe door its upper end wil be carried out on the tracks 4 and5, while its lower end will be carried up in the tracks 2 and 3 until itshall have assumed the osition shown in Figs. 1 and 2, where it wi beretained by the said weights and will be entirely out o'r' the way.

For securing the door when closed a spring catch 3() .ma be used, asshowiniwhich. is attached to t e upper central `portion of the Securedin the center ,of the face of the door is the ear 31, in which ispivoted one end of the spring-arm 32. When the arm 32 is not in use, itma be folded flat against the door and retained Viiy the keeper 33 overthe head of which .the arm passes, as shown. By means of said-arm thedoor may be ieasily opened andclosed manually and when closed isautomatically secured by the catch 30.

I nowicome to the descriptionof the mechanism for automaticallyoperating .the `door for fire purposes.

Secured to the wall A -slightlyto `the lett of the sheave 27 is a sheave50, over which passes the cable `or the vlike 51. The numeral 52 denotesa screw-eye located inthe side of the weight 29, through which screweyeextends one .end `of the cable 51, and secured to the cable 51 below'thescrew-.eye 52 is the small weight 53.. The `opposite end'of the cable 51is secured to the intermediate weight 54. Secured to the left of thesheave 50 on the wall A is one of the releasing devices shown in detailin Figs. 4 and 5 and which will be prese'ntly described in detail. Tothe left of said releasing device is a pair of loose pulleys 55 and 56,which are suspended from some stationary point, as the wall A.

The numeral 57 denotes a wire or the like, and numeral 58 denotes a wireorthe like, said wires being united by a fusible link, as is indicated.

The wire 58 extends thro h the pulley 56 and is then secured to the weiht 59. A central longitudinal apertureis ormed through the weight 59,and through said aperture loosely extends the wire or `cord v60, whichalso Aextends through the pulley 55 and has one end secured to the upperend of the lever 67 of the releasing device, and on. the other end ofthe cord 6() is a small weight 61. Extending up from the weight 54 is ashort cord 62, in the upper end oi" which is the ring 63, which ring isadapted to be placed over the hook 66 ol' the releasing device.Saidreleasing device consists ol' the body 64, having the arm pivotedvertically thereon, as shown, and on the lower ciid of the arni 65 nearits pivotal point is the hook 66. Pivoted vertically near the center ofthe body 64 and then extending upward is the lever 67, in the upper endand near the conter of which are lon cated the eyes c and l),respectively. In the upper endof the bod 64 is a horizontal bar 68,behind which the ever 67 passes. On the upper end of the arm 65 is acatch 69 'for enga ement behind the lever 67, as shown.

he numeral 70 denotes a helical s ring secured at one end iii the eye b,with t e other end secured to some stationary point. The tension of thespring` 7U is such as t0 allow the lever 67 to be turned to the left torelease the Weight 54 and after said weight is released to return saidlever to the position shownn in the drawings.

This arrangement of sheaves, cable, and releasing device is du heated onthe right of till; door, as indicate by the primed numera' Lt will nowbe seen that the door being up, or o en, as in Fig. l, the wire 57 beinexten ed to the desired point with fusible inks located at desiredintervals, and the other parts being located substantially as shown inig. 1 in case of the fusible links being dainaged by lire or otherwise,the wire 58 being freed, the weight 59 will be dro ped on the smallweight 61, the Wire 60 willlpull the lever 67, and it in turn by thewire will pull i the lever 67 to the left, causing the arms 65 and 65 todrop forward, releasing the weights 54 and 54. The weight of the wei hts54 and 54. will then be exerted to over alance the weight of the Weights28 and 29, whereby their weight will be added to the weight of the door,resulting in the closing of the door automatically;

My invention is ositive in its operations and accomplishes t e objectsabove stated, and it is evident that changes therein may be made wherebyto accommodate the invention to varying conditions without departingfrom the principles of the invention, and it is understood that variouschanges therein may be made as would suggest themselves to the ordinarymechanic.

Havingenow fully shown and described my invention, what I claim, anddesire to secure by Letters Patent of the United States, is-

1. A counterbalanced door operative on a vertical and a horizontaltrack, in combination with sus endedauxiliary weights, and deviceswherdb the auxiliary weights may be .released andy add their weight tothat if the door to close it automatically, substantially as set forth.
